I would say that will set it off nicely, Also the hi build primer will fill many of the little imperfections in a 17 year old car.
This is how mine is going when it gets done more than the mini.
Three layers of hi build primer flattened down,
Three layers of standard 2K primer flattened down,
Three layers ofThe correct basecoat colour mine is silver the base really sets the paint off as it is semi transparent.
Then 9-10 coats of colour with extra metallic flake in the last two coats.
2 layers of 2k super clear metallic laquer
4 layers "glass shine" 2K laquer
Hand finished by very good bodywork guys

I use House of Colours for my Laquers as they do all the American hot rod colours expensive but really really good.
My Mini nearly went electric cobalt blue but at £200 a litre it went Kawasaki violent pearlescent blue which is a really nice colour bit girly tho!!!
